IMPROVED QUARTZ-CRUSHER..

Specification forming part ofLetters Patent No. 43,304, dated June 28,1864.

To all whom it may concern:

Be it known that we, DAVID GAY and JOHN H. PURKISS, of Long Bar, in thecounty of Yuba and State of California, have invented a new and usefulVImprovement in Hydraulic Quartz Crushers; and we do hereby declare thatthe following is a full, clear, and ex 1ct description of the same,reference being had to the accompanying drawings, making a part of thisspecilication, in whichv Figure l is a side elevation 5 Fig. 2, a plan.

This invention consists in the attachment of a waterwheel to the side ofthe ordinary crushing-wheel of a Chillian mill,7 so that the saidwater-wheel will travel around in the same path as the crushingwheel,and will furnish motive power for driving thc mill. Each crushing-wheelmay, if desired, have two water-wheels attached to it, one upon eachside of the crushingwheel, as indicated in red outline, Fig. 2.

Quartz-mills made according to our improvement may have one, two, ormore crushingwheels and attached water-wheels, according to the supplyof water or the requirements of the builder.

The foundation A, annular basin B, in which the crushing-wheels move,and the central pivot, G, around which the crushing-wheels D travel,are, together' with the wheels D, constructed in the ordinary manner,well understood by practical mill-wrights. Upon the inner side of eachcrushingwheel D we attach an overshot water-wheel, E, which is constructed according to any of the well-known methods. As shown inthedrawings, the buckets F are attached to an inner drum, G, the bucketsand drum being arranged between two tlan ges, H H. A horizontal shaft,I,passes through the crushingwheels D, and also through the water-wheelsE. This shaft has an eye or aperture at its center, where it receivesthe central pivot, C, as shown in Fig. 1. Each crushing-wheel and itsattached waterwheel turns loose upon shaft I. Between the twowater-wheels and rising from the shaft C are two standards, K K, uponthe upper extremities of which is mounted a water-trough, L, whichextends across over both waterwheels. There is an aperture, M M', ateach end of this trough L, but on opposite sides. When a running streamor supply of water is allowed to flow into the trough L, the waterissues through the apertures M M upon the buckets of the water-wheels,as shown by the arrows, and sets them in motion, thus causing thecrushing-wheels also to move and travel around in the basin B and crushthe quartz contained therein. Thus the crushingwheels, water-Wheels, andsupply-trough, together with the horizontal shaft I, all move together.As the wheels revolve the Water brought down in the buckets isdischarged upon the aprons N, one of which is placed in front and at thelower part of each Wheel E, the aprons N being supported by arms O O,which are saddled across the central shaft, I, in the manner shown inFig. 1, a filling-block or bar, S, being placed between shaft I and thebars O, as shown in Fig. 1. The aprons N receive and conduct the wastewater away from the wheels into the sewer pipes P, and

thus prevent it from flowing into the basin B.-

To assist in conducting the water toward the pipes P, the central partof the foundation Q is made concave, as shown. The outer edge of thebasin B is provided with a perforated screen, R, to prevent the undueescape ofthe quartz. The mill is also to be furnished at other pointswith the channels, sluices, screens, and pockets necessary or convenientfor such machines, to assist in saving or preventing the waste of thesubstance to be crushed.

This mill may be used for crushing all kinds of ores and othersubstances.

We do not confine ourselves to any particular details in theconstruction of our mills, be cause these may be varied according to theordinary skill or desire of the mechanic or owner.

Having thus described our invention, what we cla-im as new, and desireto secure by Letters Patent, is

1. The attachment of the water-wheel to the side of the crushing-wheel,substantially in the manner herein shown and described, so that thewater-wheel will drive and travel with the crushing-wheel, all as setforth.

2. The combination,` with the water-wheels, of the water-conductingaprons, substantially as herein shown and described.
